quickly and economically. Socket-welding reducer inserts
serve the same purpose as threaded reducing bushings
with threaded fittings.

To minimize the possibility of cracking of the fillet welds, it is recommended that the
shank portion of the reducer be withdrawn approximately 1/16 in. (1.6 mm) away from
the contact with the bottom of the socket before starting the weld. Likewise, the pipe
is to be kept away from contacting the bottom of the reducer socket before welding.

12. FORGED STEEL CATOLETS
CATOLETS PROVIDE A STRONG BRANCH PIPE CONNECTION, CONSIDERABLY STRONGER THAN A WELDED PIPE-TO-PIPE CONNECTION.
CONSEQUENTLY, WITH GOOD WELDING PROCEDURES, CATOLETS OFFER GREATER RESISTANCE TO DISTORATION AND BURSTING.
CATOLETS READILY AND ECONOMICALLY PERMIT THE ADDING OF BRANCH CONNECTORS TO EXISTING PIPING INSTALLATION,
ELIMINATING THE (RELATIVELY HIGHER COST OF) CUTTING OR DISASSEMBLY AND REASSEMBLY REQUIRED FOR THE INSTALLATION
OF TEES. CATOLETS OF THE SAME OUTLET SIZE AS A HEADER OR RUN PIPE SIZE(I.E"FULL SIZE" CATOLETS) ARE SO PROPORTIONED
THAT THE (ELLIPTICALLY-SHAPED) HOLE IN THE HEADER PIPE HAS THE MINIMUM WEAKENING OR DISTORATION EFFECT,
AND YET PROVIDES GOOD FLUID FLOW CHARACTERISTICS.
SPECIFICATIONS
CHEMICAL AND PHYSICAL PROPERTIES ARE RIGIDLY CONTROLLED TO ENSURE CONSISTENTLY HIGH QUALITY. PHYSICAL AND
TRACEABILITY OF CHEMICAL TEST REPORTS ARE AVAILABLE ON REQUEST. INDIVIDUAL CATOLETS CAN BE ESTABLISHED THROUGH
THE HEAT CODE OF EACH FITTING. CATOLETS MEET THE REQUIREMENTS OF MSS STANDARD SP-97. THEY ARE FORGED FROM STEEL
WHICH COMPLIES WITH ASTM A105.

CATOLETS ARE DESIGNED TO HAVE NO MORE THAN A 1/16"GAP BETWEEN THE BASED OR SKIRT OF THE CATOLET WHEN IT IS SEATED
DIRECTLY UPON THE APPROPRIATE RUN PIPE. IT IS RECOMMENDED, HOWEVER, THAT THE SKIRT OF CATOLETS BE HELD SLIGHTLY
ABOVE THE RUN PIPE AND TACK WELDED TO PROVIDE A SMALL CONTINUOUS ROOT GAP BETWEEN THE SKIRT AND RUN PIPE BEFORE
COMPLETING THE ALL-AROUND WELDING BEADS OR FILLET.
